Which of the following is NOT one of the pillars of the Philippines' National Security?

In approaching the question, we can identify the pillars of national security in the context of the Philippines. The main pillars typically include aspects such as economic security, political security, environmental security, and military security.

Among various options that could relate to national security, it's important to choose the one that does not fit within these established categories. Options such as "social security" might be misleading, as it could be confused with economic or political security.

Therefore, without the listed options, I’ll state that the one that does not commonly belong to the recognized pillars of national security is often "social security."

If you have specific options to choose from, please share them for a more precise answer!
